"Let's be honest here. When most of us think of open source and free software, we really aren't thinking of something flashed to a BIOS ROM chip. And yet when it comes to the Linux BIOS project - that's exactly what's happening here. The LinuxBIOS is a project designed to work out any perceived shortcomings from existing BIOS options distributed on today's motherboards. Started back in 1999, it has been in development steadily for quite some time now."

I'd say EFI is more likely to supplant the BIOS in the long run for the majority of motherboards these days. LinuxBIOS will probably be relegated to low cost motherboards or custom-made motherboards that are developed to be totally free from EFI or BIOS limitations. LinuxBIOS makes sense in some situations, but not all by a long shot.
